A randomized trial comparing adjunctive Modafinil with placebo for clozapine related
adverse effects in people with schizophrenia or schizoaffective disorder in remission.
Information sheet
You are being requested to participate in a study to see if a drug called Modafinil can help you
with the side effects of increased sleepiness and increased saliva formation caused by Clozapine
that has been prescribed to treat you. These are common side effects of Clozapine and many
people given Clozapine suffer from these problems. There are other drugs that can help with
these but we do not know of any that can help both at the same time. We hope to include
about 70 people from this hospital in this study.
What does Modafinil do when taken along with Clozapine?
We have observed that when people who are sleepy in the daytime and sleeping long hours at
night on Clozapine are given Modafinil, it keeps them awake and alert during the day. Modafinil
has also helped reduce and even stop the increased salivation that had been a problem with
Clozapine treatment. Modafinil also reduces appetite and many people lose some or all of the
weight they had gained while taking Clozapine. However, we have only used this for a few
people taking clozapine and we need to use it for more people to be sure it really helps
Does Modafinil have any side effects?
Modafinil has been used by many people all over the world to help reduce excessive sleep due
to a variety of problems, including that caused by medicines. The majority of people have not
had any side effects. Some people on Modafinil have experienced some side effects such as
headache, feeling anxious, feeling like vomiting, loose motion and stomach discomfort, but
these were usually mild and temporary. Modafinil does not cause addiction or any problems
when it is stopped suddenly. It may cause mild increases in blood pressure but these are usually
not serious. It is not known to cause any problems to the heart. Rarely, it can cause a worsening
of the psychiatric problem but this has been observed only at doses higher than what we plan
to use in this study.
If you take part what will you have to do?
If you agree to participate in this study, you will be given either one table of Modafinil to be
taken every morning, or an identical looking tablet that does not contain Modafinil, for a total
period of 9 weeks. Using thus dummy tablet will help us be sure that any improvement in your
sleepiness or increased saliva formation is actually due to Modafinil and not due to chance
(coincidence) or normal fluctuations in your condition. Neither you nor your doctor will have
any choice in whether you will get Modafinil or the dummy tablet as this will be decided by a
computer program; this is like tossing a coin and you have an equal chance of getting either
tablet. Also, neither you nor your doctor will know which tablet you are taking till the study is
over.
All other treatments that you are already on will be continued and your regular treatment will
not be changed during this study. You will be expected to come for a review to the hospital 2
weeks after starting the tablet and again after 4 more weeks and finally after a further 4 weeks.
Before starting the study and at each visit you will be asked questions about your sleep, saliva
formation, activities, how you feel and about any side effects. Your weight and blood pressure
will also be recorded at each visit. No additional procedures or blood tests will be conducted
routinely for this study.
If at any time you experience any problems, you will be expected to report this to the doctor.
You will also be contacted by telephone at least once in between the monthly visits by the
doctors in this study who will ask you about any side effects you are experiencing.
Can you withdraw from this study after it starts?
Your participation in this study is entirely voluntary and you are also free to decide to withdraw
permission to participate in this study. If you do so, this will not affect your usual treatment at
this hospital in any way. In addition, if you experience any serious side effects or your condition
worsens, the study tablets will be stopped and you may be given additional treatment.
What will happen if you develop any study related injury?
We do not expect any injury to happen to you but if you do develop any side effects or
problems due to the study, these will be treated at no cost to you. We are unable to provide
any monetary compensation, however.
Will you have to pay for the study tablets?
Both Modafinil and dummy tablets will be given free for a total period of 9 weeks. We will also
reimburse you and one person accompanying you the money that you spent on travel to come
for review (please keep your bus or train tickets) for the visits that you make for this study.
Any other treatment that you usually take will continue but the usual arrangements that you
have with the hospital will decide how much you pay for this.
What happens after the study is over?
You may or may not benefit from the study drug that you are given. Once the study is over, if
the tablet you were given is Modafinil and if it has helped you and you wish to continue, then
your doctor may prescribe it for you. If you were given the dummy tablet and Modafinil has
helped the people who took it, then your doctor will give you the choice of taking Modafinil.
However, this will not be part of the study and you may have to pay for it.
Will your personal details be kept confidential?
The results of this study will be published in a medical journal but you will not be identified by
name in any publication or presentation of results. However, your medical notes may be
reviewed by people associated with the study, without your additional permission, should you
decide to participate in this study.
If you have any further questions, please ask Dr.XXX, Dr. XXX or Dr. XXX (tel: 0416 228XXX/
